relative formula mass of MgCO3
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
For mass % only the mass is required for this calculation. When only moles are known, than also molar composition - formula and atomic- or molecular masses are needed to calculate % of composition
The chemical formula of potassium dichromate is K2Cr2O7; and the molecular mass is 294,185.
The chemical formula is (NO3)-; the mass is 62 g.
